 Post subject: zaurus的录音功能

前面讲了如何使用z机的麦克风做语音录音。

这样,我们已经开始接触到声卡。这就让许多工程师有了新的联想,没错,那就是虚拟示波器。

虚拟示波器也是很贵的,最差的也要2000左右,好的大牌子那就不用说了。

不过,现场工程师跟研究室里边还是不一样的,通常都只是处理一些低频率的信号,如语音300-3kHz,串口通信9600bps。也不需要对信号做很高质量的研究,只是看看信号有没有,是否受到干扰,所以这些情况下,普通的声卡,例如z机的完全可以胜任。

现在硬件不会有什么问题了,主要是要找一个能显示波形waveform的软件,不幸的是,z机上没有这样的软件。

找到最接近的可能就是这个东西:
http://xoscope.sourceforge.net/

也许那位朋友可以编译研究下。

在Z机上编译没有?

 Post subject: oscope的编译要求

* 需要一个混频软件来选择信号源和音量,例如"gmix", "xfmix", "xmix", and "aumix". (注:应该不重要)

* 需要"GTK+"编译X界面(强烈推荐)。

* 或者使用"libsx"如果没有GTK+。

* 如果是编译svga模式的版本,在命令行下面运行,需要svgalib里边的libvga. svgalib是没有X的时候,在原始的命令行模式下面使用vga的接口,现在一般都用fb代替,比vga简单。

* 如果是编译svga模式的版本,需要g3vga里边的libvgamisc来显示text,估计是个字库。

不直到PDAXROM下面能不能编译?

这东西要是真编好了,可称得上是电子工程师的福音了。

有关显示波形

你可试下这个软件 http://www.milkytracker.net/download.html
正好有Z版

这是一个做音乐的软件,但是可以LOAD SAMPLE(WAV格式) 并且内置一个SAMPLE EDITOR...可以看波形,但非常简陋,而且麻烦.....


PS.我用的PC版,这个Z版还没试过...

下载后在C1000,Cacko 1.23下安装正常。
运行后死机了。

sl5500好像可以,初看是屏幕问题。

mic做示波器粗糙了点。尤其是接到电路里面是需要衰减的。真正要分析一些东西,还要加上很多算法,fft什么的。可以专门做一个项目了。


palm还是ppc上有个红外频谱分析仪,也挺有趣的。
